Request failed; target reset (Error 171)
Cause: During a monitor command, the target system asserted (and continues to
assert) the reset signal; the monitor is no longer responding.
Action: Prevent your target system from asserting the reset signal when you are
using monitor commands.
Request failed; unexpected exception: <vector number> (Error 171)
Cause: The monitor was executing a command and some exception occurred that it
did not expect. During monitor command execution, the monitor traps all
exceptions by using its own stack and vector table. The monitor provides exception
handlers for some exceptions, such as access fault, so that it can either recover or
issue a detailed error message. The monitor had no exception handler for the
exception number shown in this message.
Action: Reset the emulator and try your command again.
Restricted to real time runs (Error 40)
Cause: While the emulator is restricted to real-time execution, you have attempted
to enter a command that requires a temporary break to the monitor for processing
(such as a request to display target system memory locations). The emulator will
not allow temporary breaks while the emulator is in the reset state or while the
target program is running.
Action: Break to the monitor using the break command, and then execute the
desired command or disable the real time mode.
Retry limit exceeded, transfer failed (Error 412)
Cause: The limit for repeated attempts to send a record during a transfer operation
was exceeded; therefore, the transfer was aborted.
Action: Retry the transfer. Make sure you are using the correct command options
for both the host and the HP 64700. The data communications parameters need to
be set correctly for both devices. Also, if you are in a remote location from the host,
line noise may cause the failure.
